Emkhiqizweni wanamuhla wezimboni, ukuphakamisa izinto ezinzima kuyingxenye ebalulekile. Futhi ama-cranes amabhuloho, ikakhulukaziama-cranes ama-double girder overhead, sebeyimishini ekhethwayo yokuthwala kanzima ezinkampanini eziningi. Uma ubuza ngenani le-double girder overhead crane, kubalulekile ukuthi ungabheki kuphela izindleko zokuqala kodwa nezindleko zokulungisa eziqhubekayo.
Umthamo wokuthwala onamandla:I-double girder overhead crane, nesakhiwo sayo semishayo emibili eyinhloko, inamandla okuthwala anamandla kunokhrayini bebhuloho elilodwa. Ngesikhathi senqubo yokuphakamisa okunzima, isakhiwo se-double beam singahlakaza ngokuphumelelayo umthwalo, sinciphise ukucindezela kwe-beam eyodwa eyinhloko, futhi siqinisekise ukuzinza nokuphepha kwe-crane.
Ibanga lokusebenza elibanzi:I-double girder overhead craneine-span enkulu futhi ingamboza uhla olubanzi lwemisebenzi. Ezingqungqutheleni ezinkulu noma izikhathi ezinezikhala ezinkulu, ingahlangabezana nezidingo zokukhiqiza futhi ithuthukise ukusebenza kahle.
Isivinini esisheshayo:I-double beam bridge craneinejubane elisheshayo lokugijima, elivumela ukuthuthukisa ukusebenza kahle kokukhiqiza. Ngesikhathi senqubo yokuphakamisa okusindayo, isivinini sokugijima ngokushesha singathuthukisa ukusebenza kahle, sinciphise umjikelezo wokukhiqiza futhi sinciphise izindleko zokukhiqiza.
Izindleko zokulungisa eziphansi: Isebenzisa ukwakheka kwe-modular, isakhiwo esilula nokugcinwa kalula. Uma iqhathaniswa nezinye izinhlobo zama-cranes, inezinga eliphansi lokuhluleka kanye nezindleko zokunakekela eziphansi.
Ukusebenza kokuphepha okuphezulu:I-double beam bridge craneibheka ukuphepha ekucabangeni ngokugcwele ekuklanyweni kwayo futhi ifakwe izinto ezihlukahlukene zokuvikela ukuphepha, njengezikhawuli, izinto ezixhumanisayo, izinkinobho zokumisa izimo eziphuthumayo, njll., ukuze kuqinisekiswe ukuphepha kokuphakamisa imisebenzi.
Lapho uthenga i-crane, abasebenzisi kufanele bakhethe i-crane yebhuloho le-double efanelekile ngokwezidingo zangempela zokukhiqiza kanye nesabelomali ukuze kuthuthukiswe ukusebenza kahle kokukhiqiza nokuqinisekisa ukuphepha kokusebenza. Ukuze uthole isilinganiso esinembile se-I-double girder overhead crane intengo, kungcono ukuthintana nomkhiqizi ngokuqondile ngemininingwane mayelana nezimfuneko zakho ezithile.
